40-180 & 40-190 restore
#4

It's a circleless tube.
No I haven't but doesn't seem too difficult and no odd parts to obtain. The phasing of the output transformer might be critical, if not phased properly the amp may just oscillate. It's just a matter of reversing the wires on the secondary no big deal.

When my pals were reading comic books
I was down in the basement in my dad's
workshop. Perusing his Sam's Photofoacts
Vol 1-50 admiring the old set and trying to
figure out what all those squiggly meant.
Circa 1966
Now I think I've got!
